To all whom t may concern..-

Be it known that I, JosIAH L. CRUDUP, of Tampa, Hillsborough county, Florida, have made certain Improvements in Mosquito-Canopies, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this speciiication, in which- Figure l represents a bedstead with myimproved canopy swung down to cover the same and also when swung up in a position not required for use. Fig: 2 is a rear elevation with the frame swung up. Fig. 3 represents, enlarged, a spring of peculiar form, upon the resiliency of which the action of my canopy depends 5 Fig. 4, a longitudinal vertical section through the holder with a portion of the spring therein. Fig. 5 represents the bracket by which the holder is attached to the rear of the bedstead. Fig. 6 represents the frame detached with a tube for uniting its upper ends; Fig. 7, atran'sve'rse section through the holder with the lower end of one branch of the frame pivoted thereto. l

My invention has particular reference'to that class of vmosquito-canopies adapted for application to beds and other objects whether the frames of said canopies be secured directly to the same or to the Wall or other contiguous support; and this invention consists in the coordination and arrangement'of the three followin ginstrumentalities-viz.,a bowshaped spring, a frame for the canopy, and a common holder for both-the construction and operation of the various parts being hereinafter described and claimed.

In the said drawings, Fig. l, A represents a bedstead, at the outersides of the headposts of which are located a pair of holders B B of the form seen in Fig. 3, each holder having a bracket a integral with and projecting from its inner side, by screws Z7 passing through which, and it is fastened to the rear of the contiguous post, Figs. 2, 3, and 5.

C C are two springs formed of circular rod or wire of suitable size to insure the resiliency required for the purpose and position to which it is to be applied. Each spring C is substantially of the form seen, being of bowshape between its terminals c d, Figs. 3 and 4, one, c, of which after passing through the holder B projects above the same at one side and is provided with an eye e for the passage of one branch h of the canopy-frame D, which eX- tends down and is pivotedE to the holder at o', while the other terminal d of the spring preferably passes through at the other side of the samewithout projecting above it. Through the forward end of each holder B passes a screw l, which is intended as a clamp for preventing the separation of the sides of the holder at this point, which might otherwise occur by the movement of the spring C therein, and for preventing the undue play of the terminal cl a wedge m is located between it and said screw Z. (See Figs. 3 and 4.)

The two opposite branches h h of the frame D are united by a tube fn., which is fitted over and slides upon the short horizontal portions p, projecting from their ends, which construction permits of the ready adjustment of the horizontal portion of the frame to supports of different widths, and also enables the parts of the frame to be separated and be more economically packed for transportation.

r is a cord the ends of which are secured to the frame at the junction of the tops of its branches 7L h with their connecting horizontal portion. The bight of this cord and an extension and tassel s, which may be attached thereto, hang down from the center of the frame within convenient reach of the hand and enable the frame 'to be depressed, and the same is held with its netting over the bedstead by passing the cord under a hook t or other device secured to the foot-board.

When the frame is depressed and secured in its lowered position, the pair of springs are made to yield and assume the position seen dotted in Fig. 3. The depression of the frame increases the tension of the springs, and their resiliency, when the frame is liberated, returns it to its upright normal position (see Figs. l and 2) with the netting'u, draped and pendent therefrom.

My herein-described invention may be applied directly to a wall contiguous to a bed, dining-room table, or to supports located in the ground or elsewhere, and affords a reliable protection from flies, mosquitos, dac., in many situations.

I claim- As an improvement in canopy-frames and their attachments a holder B and abow-shaped IOO spring C having two straight portions located eupy when required for use, substantially as Within said holder, the bow of the spring bedescribed. ing below the same, and the terminal c of the fitness my hand this 29th day of January,
